答案 Sea Ice Sea ice surrounding Antarctica reached a new record high extent this year. / It covers more of the southern oceans than it has / since scientists began a long-term satellite record/ to map sea ice extent in the late 1970s. / However, the upward trend in the Antarctic / is only about a third of the rapid loss of sea ice in the Arctic Ocean. / The new Antarctic sea ice record reflects / the diversity and complexity of Earth’s environments. / A senior scientist has referred to changes in sea ice coverage / as a result of global climate change.
解析     本文主题是海冰。文章中涉及the Antarctic和the Arctic Ocean等专有名词，听写时注意专有名词首字母应大写。文中出现的难词主要有satellite，diversity，complexity。第一句中，注意surrounding作为sea ice的后置定语的一部分要用现在分词形式，且整个句子的时态为一般过去时，故应注意reached用过去式。第二句句子较长且句式复杂，than引导的从句中又包含着since引导的时间状语从句，在听写时要注意根据停顿来辨认句子结构。
